Remarks.
The ZSI collection has one glass bottle for this species. It contains the ‘type’ (female from Tindharia), which is partly dried off with detached opisthosoma and without legs, except the right leg II and posterior segments of right leg III. The epigastric region including the epigyne is peeled off and remained at the bottom of this bottle. We failed to trace the second female specimen from Punkabari, Darjeeling, which may either be lost or misplaced elsewhere in the collection.
Gravely (1931)
described this species based on two
syntype
females. Detailed examination of one
syntype
of
C
.
himalayensis
suggests that this species has all of the diagnostic features of
C. severum
: gradually widening opisthosoma, which is widest and truncate near the anterior tip, trapezoid epigynal plate, medio-laterally placed copulatory openings, transversely oriented copulatory ducts with a 90° bend near the spermathecae, and the spermathecae with hook-like anterior and globular posterior parts (cf.
Fig. 2
A–C and
Deeleman-Reinhold 2001
: figs 464, 467–468). The species
C. himalayensis
syn. nov.
should thus be regarded as a junior synonym of
C. severum
.
